how to create 3d model with separate model materials
hello, excuse me if my English not good.
i'm new in creating 3d models, so i use this sh3d to create plans because it's simple yet powerfull, and freeeeeeeeeee.
as stated in the topic, i'm having trouble creating 3d model using FreeCAD (new too) to import it in sh3d, my 3d model only has 1 model material like the picture below,
i want my 3d model has separate model materials to edit color or texture like this one
btw this is my 3d model in FreeCAD
please tell me where i'm wrong in the process and what i must do to make my 3d model has separate model materials. thankyouuuu
